Application filed October 12, 1912. Serial No. 725,449.

To all whom t may concern Be it known that I, DAVID F. FnIsrNGER, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Manual Motors, of which the following is a. full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, referH ence being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side elevation partly in section showing my device as applied to a boat. Fig. 2 is a top view. Fig. 3 is a plan view partly in sec-tion on line 3%-3 of Fig. 1.

My invention relates broadly to boat propulsion and specifically to a form of manually operated propulsion mechanism adapted to be applied to small boats.

The principal object of my invention is to provide a simple and economical device for propelling small boats by hand power, which may be readily applied to divers forms of boats which may not be designed primarily for the device.

A further object of my invention is to provide such a device which includes features rendering it adjustable so? as to accommodate it to the convenience of the operator.

A still further object of my invention is to provide a device for the purpose described of a construction such as renders it readily attachable and detachable.

With these objects in view, I provide a base plate 1 which is adapted to be posideck or foot boards 2, of a tioned upon the boat 4. Upon the plate 1 is supported a hollow standard 5 which may be reinforced by a brace 6. Slidably positioned within the hollow standard 5 is a bar 7 which carries at its upper end a cross arm 8. Upon the aft portion of the cross arm 8 is journaled a shaft 9 which carries a beveled gear wheel 10 and a pair of cranks 11 by which the gear wheel 10 may be rotated. Journaled upon the forward portion of the cross arm S and extending at right angles to the shaft 9 is a shaft. 12 carrying the beveled gear wheel 14C which meshes with the gear wheel 10. Upon the forward end of the shaft 12 and normal thereto is carried a sprocket wheel 15 which extends beyond the end of the cross arm 8. A propeller shaft 16 is adapted to be journaled upon a portion of the boat structure and carries a sprocket wheel 17. A suitable chain or belt 18 is adapted to transmit power from the wheel 15 to the shaft 16. rIhe shaft 16 passes out of the boat through the stuing box 19 and carries the propeller 20.

As a means for attaching the device to the boat, I provide transversely disposed rods 21 which are attached to the boat and equip the plate 1 with the lugs 22 and the cla-mp 24 which are adapted to cooperate with the rods 21. In attaching the device, the lugs 22 are hooked under one of the rods 21 and the clamp 2.4 is then hooked under the other rod and tightened so as to secure the device in place.

The bar 7 is provided with the toothed portion 25. IVith it cooperates the toothed pinion Q6 which is suitably journaled on the standard 5. The toothed pinion 26 may be turned by any suitable means 27 and when thus turned will operate to raise or lower the ba-r 7 within the standard 5 by virtue of its engagement. with the toothed portion 25. A dog 28 is provided to retain the bar 7 in elevated position which it may do by cooperation with the serrations 29. The elevation of the bar 7 operates to elevate the cross arm S and the parts carried thereby for the purpose either of taking up slack in the transmission chain 18, or for the purpose of accommodating the' device to different sized operators or to different sized boats. For the purpose of accommodating the transmission chain to the adjustment, links may be removed or inserted.

The propeller which I prefer to employ is formed with a cast hub portion 30 in which are set blades 31 of some light material such as sheet steel. Such a propeller is most easily operated by the device shown, although it is obvious that other forms of propellers may be employed.

In the use of my device the operator who may be seated upon the seat 39, grasps the handles 3A of the cranks 11 and rotates the gear 10. The rotation of the gear 10 actuates the gear 14 which operates the propeller shaft by virtue of the connecting transmission gear.

By the use of my device, I am enabled to secure a very rapid rotation of the propeller with but little manual effort, as the relative size of gears 1() and 14 or 15 and 17 may be such as to cause the rapid rotation of shaft 16 with a comparatively slow operation of shaft 9.
